putting a 3.3 in my SC

[diverdan]

Would a Subaru manual transaxle work in a boxster with the Subaru engine? I ask this as there are probably a number of failed tiptronic boxsters out there. The cooling plumbing and fabrication would be easy, but what about the conversion for a flipped tranny and clutch actuation? Is the Subaru tranny within space limitations?

For all the critics of such mods: Yes one off fabrications are expensive and depend upon the skill of the craftsman. However, some of the most popular threads have dealt with modifications and even those other than Porsche.

Keep up the good work.

The problem with the Subaru transaxle is that it would need to be converted to 2WD only. This can be done, but I haven't taken any measurements on the Subaru transaxle to see what they would fit in...if anything. I think the next thing I am gong to bastardise is a Boxster so keep tuned in for a future build.

The Subaru trannies aren't really much different dimensionally than a G50. The 914 guys doing Suby swaps have started to use them. They are installing both the 2wd ones from early 90's Legacies as well as AWD ones that have the center diff removed. There's an operation in Australia that's making a block off plate, though it wouldn't be terribly hard to make your own.

There's also a 914world member, who may or may not also belong here, who has had custom CV's made so that you can made the Subaru output flange to the 914 axles. They should be to market in pretty short order from what he tells me.

This whole Boxster thing is something that had been batted around on NASIOC for a bit. I think there's a potential for a market for a kit on this one. Not with the Subaru tranny though. Personally, I don't know that it would go for a Suby tranny if going that route. It would be an easier swap using the G86 tranny and making up some sort of KEP style adapter plate for the Subaru engine. I don't really think it would be a terribly hard converion when it comes down to it. It would just have a lot of wiring. However, it would really be no different than putting a WRX engine into an old Impreza in that respect. The whole thing would very likely run you less than a cost of a rebuild and with all of the issues they have on the early Boxster engines, it may be a really good alternative solution.

Lastly, someone mentioned something about Renegade telling them they couldn't do a 4 banger Suby swap in their 912. That's just that Renegade doesn't do it. They looked at it and decided it wasn't viable for them. However plenty of people have done this swap and it's not much different than putting one into a vanagon or a beetle. Look to Wayne Siever's car for an example if you want to pursue it further.

In regards to the 912 conversion... Back in 1995 before it was popular to use Subaru engines in off road vehicles, I installed a 2.2 subaru engine in my sandrail mated to a 091 VW bus transaxle. I used a Kennedy adapter plate and modififed flywheel and that engine, after installing 50 lb injectors, a new and programable computer, turbo and intercooler produced 350 HP at the flywheel. About 2 years ago, I switched long blocks and now have a 2.5 single overhead cam engine. HP is now 368.

I know for sure that it will fit in a 912.

AMAZING. What you are doing with YOUR car is truly inspirational and your skills could easily match up with the most skilled P-car purist here or anywhere.

Thanks for sharing this with us and please continue to do so as most of us simply dont have the time or skills to perform this kind of magic on a car, but watching you do it is truly thrilling.

[kcpaz]

Well so far I have logged about 600 HARD miles (I'm not trying to brake something, but I'm expecting going to baby the thing either) and I have absolutely no problems at all. No leaks, no misfires, no stalling, no over heating and no broken parts. The only stored code in the ECM is for the EGR temp sensor (the car has no EGR system anymore).

The transmission needs a rebuild but that's really the only complaint I have so far.... oh and the suspension needs an overhaul. I'm thinking sway bars, torsion bars, bushings, and lower ride height. I'll probably do a Patrick Motorsports weld-in roll bar too Then it's off to the track|!

[2guard]

first off, awesome work.
was wondering if you've had any experience with the ej20 turbo engine. I figure if I'm going to bastardize a porsche, why not go all out. and besides, less weight for the 2.0 I'm guessing (around 330lbs for the engine), means more power. I had a 2.7 in my 72 and sold it to upgrade, but not really that excited about buying another. just wondering if you are going to fab some engine cradles and sell them, and how much would be innolved to convert them to an ej20 mount.
again, awesome work.

[kcpaz]

The EJ20 would require a completely different engine mount system, and to be honest, I have no interest in building a 4 cylinder 911. I will however do an EZ30 6 cylinder build next. The EZ30 is almost the same size as the 4 cylinder engines and can be boost friendly. I'll let you guys know when I get that project started.

[Yellowbird RS]

how much for the engine mount and the wire harness and headers? I maybe going to "aru" a 911 to do some open road (rally) races

[kcpaz]

I'm not yet 100% committed on building parts to sell yet (I'm waiting to see how much interest there is) but I can tell you some estimated prices based on what I already know...

Engine mount system will probably be around $300-$400 because of it's complexity (I may decide to offer a rubber mounted version)

A modified Subaru wiring harness usually runs in the $800-$900 range. A stand alone system may prove to be a more cost effective route. I'm looking into an SDS system

A pair of headers is going to be in the $800-$900 range and slightly more if ceramic coated. These would be 1 5/8 in primaries into a merge collector and exit to 2 1/2 in V-band. Stainless could also be an option but then it gets really expensive.

A complete cooling system which would include a custom aluminum radiator, sheet metal, twin spal fans, fan controller, and air bleed valve would be in the $1000-$1200 range

If these prices seem high, it's because we are talking about limited production, hand made parts. This is just to give you an idea how much of an investment it would be up front.

[Starless]

This gave me an idea....i'm gonna put my 3.0 in a Justy
Now we're talking!

[EG 33 Baja Bus]

Hi kcpaz , i was just cruising around on the net this morning and found this great thread which interests me mainly due to your EG33.
Like you i have gone down the conversion route and have fitted my EG33 in a 1977 Baja'd VW Kombi , which after a few short drives is bloody fanatastic to say the least compared to the old 52 bhp flat four.
Sorry i didn't have time to read your hole post as yet but my question to you is , you seem to have tried to make the extractor pipe lengths the same on the front and back cylinders on each side but the middle cylinders are some what shorter .
I have much the same in my extractors mainly due to the limited room etc , but was just wondering why yours are like this.

Cheers Andrew

[kcpaz]

Like you, I had to do it that way because of space constraints. My plans are to go with forced induction in the future, so I'm not too concerned with it.

[lateapex911]

Glorious sound!

I read the whole thread and .....hard as it was, I've kept my mouth shut. The comment from the guy criticizing the project because of the look of the intake casting nearly put me over the edge. Talk about missing the forest while staring at a tree!

You should be proud. As should your parents. You've attacked a project..and seen it thru, that in itself is something to be proud of...most of us drop the ball. Secondly, you are passionate, but balanced. And you're well spoken (or, in this case, well written). Finally, you appear to have a good attitude, and the project reflects that. You seem beyond your years.

The exhaust is quite nice. Overall, the fab is well done. That said, there are a couple points where i would have taken a different route, but, you've reasoned through your decisions quite well.

If I could change one thing, it would be to hide/move the alternator....but, all in all, thats a pretty minor complaint!

Nice job...and be sure to start a thread on your next project!

[kcpaz]

Thank you for the kind words good sir. It's nice to hear positive feedback from a senior Pelican. I think having a well rounded outlook on life makes for a pleasant attitude. I really like Porsches, but I LOVE all kinds of motorsports too.

I've had thoughts of a 3.6 964 conversion, but to be honest, I love the car the way it is, and it's uniqueness... although a G50 would be nice

[hcoles]

IMHO - I'm very impressed with anyone taking on a project of this magnitude. For example I'm impressed with the kids next door messing around with their 57 Chevy and not doing a very good job of it but learning alot along the way and having fun with friends..compared to some kids around here that drive a $30-40k techno sled of some sort and don't know how to check the tire air pressure. Yes you can rightfully be very proud of yourself. Like the guy at a car show I saw a few years ago in Scotts Valley, he had two V8's in some sort of old car.... a very strange design on how he got them fit in there sort of cock-eyed/etc. but I had to admire the guy for diving in to it and getting it running.

[rrnixonjr]

How about this engine in the back of a 911? 200lbs and 400 hp. http://www.h1v8.com/page/page/1562068.htm

[hcoles]

that h1v8 would be about right in a 914 - not bad for $28,000 considering they have just made a few... very interesting history on how the engine was developed.

[81turboporsche]

first I'd like to say very cool build and your craftmanship is stellar,second I'm looking toward to see that car on the road,third in the pics on the rear of youre car,is that a galant vr4 next to it,my buddy had an immaculate one and that resembles it slot

[kcpaz]

Yeah my Galant is a track car. It's still technically street legal, but it doesn't really see street use. Here are some more pictures of that car...







It's not done yet, but it's already the fastest car I've ever owned... in a straight line and around a road course.
